The present invention discloses a transparent super-hydrophobic cultural relic protection material and a preparation method thereof. The method first grafts a hydrolyzed silane coupling agent onto the surface of silica, and then utilizes the amino group of the hydrolyzed silane coupling agent to react with the carboxyl group of a chain fatty acid to graft a chain alkyl group onto the surface of silica particles. The prepared material has excellent super-hydrophobicity, a large contact angle of water droplets on the coating surface, and a small rolling angle, making it difficult for water droplets to stay on the coating surface, thereby effectively preventing moisture penetration. At the same time, due to the transparency of the silica particles and the chain fatty acid, the coating can maintain a high transparency and will not block or change the original color and pattern of the cultural relic. The silane coupling agent acts as a bridge connecting the silica particles and the chain fatty acid, which can enhance the chemical bonding inside the coating, making the coating less prone to aging and cracking, and giving the material good high-temperature resistance and the advantage of resisting ultraviolet light, thereby extending the preservation life of the cultural relic.
